Sir George Hamilton Kenrick FRES (29 January 1850 – 28 May 1939) was an English entomologist who specialised in Lepidoptera especially those of New Guinea.

After completing his education in Brighton and at University College, London, he worked for two years as an engineer at Nettlefolds in Smethwick, where his brother was a director.

Kenrick engaged with the local primary and higher education policy and at the age of 30 he became a member of the school board in Birmingham after the resignation of Dr Dale.

Both expeditions, in which hundreds of new species of butterfly (including the Birdwing Ornithoptera rothschildi) were discovered, were very successful.

Kenrick was knighted by King Edward VII in 1909, during a royal visit to Birmingham, while he was Lord Mayor.
